I would like to make a landscape, made with 5 different "shots" of the same scena in different moments of the day, assembled in Photoshop; something like that one in the attached image. I know that I have to work in the Atmospehere Editor with the Sun's Pitch & Azimuth values, but I don't understand how, maybe because at school I was really bad in astronomical geography. :=) Somebody have suggestions for the setting at the five different moments, considering that I will orient the camera to North, like this: ^ | Also, what focal lens do you think will be better, and does I need to use "Panoramic Option" in the render settings? Thanks for the help. Luca "cinacchi"

Here's a link to an older thread related to azimuth. It might help explain how it functions in Vue. You don't really need to be a scientist, just to understand the basic principle of it. The rest is trial-and-error...whatever *looks* right is probably right. :)

Hi Luca, Err..what attached image? ;) Anyhow, I'm not so sure I understand what you're asking, or what you're planning, but it sounds cool to me. :) The link above is to an azimuth tutorial bloodsong made, so that might help some. I personally like a camera focal lenght of around 22-27 mm for landscapes, though I usually just "wing it" and go with whatever looks good. Combining focal length with panoramas can be trick, though, since it all changes as you change the aspect ratio of the pic...in other words, just go with what you like, and what you think looks good. if you go with a panorama, I'd say, make it no more than 120 degrees. If you're camera gets off level, it will play hell with the horizon, so be careful about that too. In all honesty, I for one, rarely concern myself with such technical details as pitch and azimuth, and in the end, I just set up a scene to where it gets what I want to see, and any and all panoramic/focal length/sun settings are done on the spot, without thinking in terms of degrees, or anything having to do with anything technical. I put alot of thought into things such as materials and lighting, but that's about it....

hmmm... I simply detach the sun from the camera and move it to the place I want it to create the right athmosphere. Its stupidly simple, but I'm happy with it:) Phil

Oh yes, that's an important point, Phil! Be sure to UNcheck "sun always points at camera." :)

If you uncheck for the sun "always points at camera" you NEVER could get a correct volumetric atmosphere. Just try with and without, especially when you have the sun somewhere in front of the cam :-).

heyas; if you dont point the sun at the camera, how do you point it? ;) i guess you can rotate it around, but i find it easier to raise/lower the sun to get it to angle up/down, and to move it side to side to get it to shine from this way or that. and lets not forget the usefullness of just grabbing the fool sun in the main view and dragging it around ;) (in vue 4.)

"and lets not forget the usefullness of just grabbing the fool sun in the main view and dragging it around " Yep, and that's about as high-tech as I get with it...
